The unit of impedance is Ohm. It is denoted by the English letter “Z”. Z = R + j X Ohms. But transformer impedance is nothing but a ratio between total primary voltage injected for reaching full load secondary current to the rated primary voltage under secondary short condition. Hence the transformer impedance formula can be written as below.

Example Calculation. Calculate the primary impedance, ZP, of a transformer circuit if the transformer has a primary circuit with 500 turns and a secondary circuit with 1000 turns. The secondary circuit has a 2000Ω load impedance attached to it. The known values are: Primary turns, NP: 500 Secondary turns, NS: 1000 Secondary impedance, ZS: 2000Ω
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
The audio transformer works at frequencies between 20 Hz to 20 kHz. So, the operation of an Audio transformer has much wider frequency range. As discussed above, the audio transformer uses Impedance balancing technique. It is very useful for balancing amplifiers and loads (Loudspeaker and other) that use a different input or output impedances ...

Coil and transformer calculator. ... For an audio transformer, you design for the lowest frequency in your audio signal, as long as this is not more then about 100 Hz, you can use Bsat as the maximum flux density in the core. ... Here we multiply the maximum current through the coil by the coil impedance at frequency f, and then divide by √2 ...

If the impedance ratio is the square of the turns ratio, then the turns ratio is the square root of the impedance ratio. Taking the square root of 312.5 gives us a 17.7 : 1 ratio, so an output transformer with a turns ratio in this range should work.
